Questions about composite beams (Hyperlaminate)
Altair Employee Hi,
im working with carbon unidirectional tubes and i thinking to use these composites tubes as a beam ( 1D Element), but 1D elements only supports MAT1.
I can use the equivalent matrices of the composite sheel tube (2D) to simulate a 1D Beam? Someone can indicate tutorials or topics that talks about this approach, how can i use the equivalent matrices...?
I'm reading this PDF, but i don't know yet how exactly apply this in Hypermesh. (http://cdn.intechopen.com/pdfs/18866.pdf)
Best regards,
Daniel Andrade
Altair EmployeeHi Prakash,
I can model the beam in 2D, but i was thinking to do a parametric optmization, variating the distance of the beams in a truss. Only size optimization supports this in 1D elements, right?
If I use 2D elements, i will use a topology optmization to find the stress path and make a equivalent truss with tubes. After that i will make a size optimization to change the tickness and diameters to find the better configuration.
I think in both ideas the result is gonna be satisfatory, but the second one is more simple.
Thank you for your attention,
Daniel Andrade
Hi,
I dont think this is supported in current version. Maybe someone from Altair team can check regarding the same.
Instead why not model the beam with 2D?
